DUST-CATCHEB FOR AIR-PIPES.

Specification of Letters Patent.

Patented Sept. 22,1914.

Application filed February 5, 1914. Serial No. 816,759.

which th'e'following is a full, clear, and erract description.

' My invention relates to a dust catcher especially adapted to beinterposed in an air conductor pipe of a hot air furnace at any pointbetween the furnace and register. An object of the invention is toprovide an efiicient' dust-catcher of the indicated character, of simpleconstruction and adapted to be conveniently placed in position-in a wayto bereadily accessible for the changing of the dust-catching materialwhen desired.

The invention will be particularly explained in the specific descriptionfollowing.

Reference is to behad to the accompany i'ng drawings forming a part ofthis speci fication, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of a dust catcher embodying my invention,showing the same applied; Fig. 2 is a perspective view of the drum orouter casing of the device; .Fig. 3 is a perspective view of a removableholder adapted to be receivedwithin the drum and to hold cotton or otherdustcatching material; Fig. 4 is a cross section on the line 4i of Fig.1, on a larger scale; and Fig-5 is avert-ical section on the line 5-5 ofFig. 4.

In constructing a practical embodiment of my invention a drum isprovided, adapted to be interposed in an air conductor pipe, the drumbeing of any desired contour, here shown as of general globular form inthe body 10 thereof. The said body is provided with registering necks 11adapted to fit stove pipe sections A, leading from any furnace P). 'Aside door 12 is provided, hinged at one side to thebody 10, as at 12";the said door forming approximately one half the body. Any suitablefastener may be provided for the door, as for ins ance, a pivoted latchhook 13 adapted to engage a pin 1% on the fixed portion of the body.

\Yithin the drum is a separate. removable holder for the (lib t-catch ngmater'al. Said holder comprises an outer bulging wall 15 conforming ingeneral to the interior of the drum and having inlet and outlet ends forthe air, in register with the necks 11 of the drum. VVit-hin the outerwalls 15 of the holder a cone 16 is providedQthebase of the cone beingconnected with the bulging wall adjacent to the outlet end thereof andthe apex of the cone being disposed in the direction of the oppositeinlet end of the holder. The wall loand cone .16 are formed ofreticulated material; that is to say, any suitable material havingnumerous openings therethrough, wire mesh being preferably employed.Both the outer wall and the cone of the holder are adapted to containcotton or equivalent dust-catching material. In the cxampleshown, alayer 17 of such material is applied at the exterior of the wall 1.1,between thesazne and the outer drum, so that the said material isexposed through the meshes of the holder. The dust-catching material 18employed in connection with the cone 30. may be placed 'withinthelatter, as indicated-clearly in Figs. l and 5, leaving the base ofthe cone without the. i as to atford an outlet'for the {-110 through thecone adjacent to the base.

By the described'construction when the holder is in pos tion in thedrum, the air entering the inlet end of the drum will pass to theinterior of the outer wall 15 and will be deflected by the cone so thatthe air will contact with the cone and with theopposed inner surface ofthe wall 1 in passing toward the .=utlet end at the base of the cone.the cotton or ctlrer material serving to catch the particles of dust.

It willbe :QQII that the holder is removable laterally from the drum byon ing the side doc: or hinged section 12 of the drum.

t will be observed also that the registering necks 11 are carried by thebody 10 and. that the door or hinged side 12 is formed withcorresponding concave recesses 12 to conform to said necks.

Having thus described my invention. I claim as new, and desire to secureby Letters Patch:

1. A 2st catcher. comprising an outer drum having necks at opposite endsto fit stove pipe sections and having a bulging body provided with aside door: and an inner, hollow holder for dust catching material saidholder being formed with irfet and outlet ends registering \viih thenet-.1) of the. drum and having an outer bulging wall conforminggenerally-to the body of the drum, anda cone Within the said wall andunited to the latter at the base of the cone adjacent to the outlet end'of.the holder, the apex of the cone being disposed in thedireciion ofthe opposite open end of the holder.-

A dust catcher, comprising an outer drum formed at the'opposite' ends tofit stove pipe sections and having an enlarged body provided with a sidedoor; and a rem'givable hollow holder of reticulated 1naterialfivithinsaid drum, said holder comprising .anouter bulging wall, and a coneWithin the said wall, said wall cor-forming generally to the drum bodyand having an inlet end and an outlet end adjacent to the ends of thedrum, the reticulated conevbeing united at its base to the reticulatedWall adjacent to the outlet end, the apex of the cone being disposed inthedirectionof the inlet end, and a dust-catching material. held by saidcone and Wall.

Y ,3. A dust catcher, comprising an outer apex of the cone beingdisposed in the'direc- 1 tion of the inlet end, and dust catchingInateria-l held by said wall and cone.

ah A dust collector comprising a drum having inlet and outlet necks atopposite ends. to fit pipesections and having a bodyof. increaseddiameter between the necks, an inner hollow holder for dust catchingmaterial, said holder'being' formed with inlet and outlet 'endsregistering with the necks of the drum, and having an outer foraminouswall of increased diameter between the said inlets and outlets, toconform generally to the body'of the drum, the holder having also aforaminous cone supported within and spaced from said wall, the taperingend of the cone being disposed in the direction of the inlet of theholder:

dust catching material in said. cone, and

dust-catching material between the foraminous Wall andth drum.

'5. In a dust ca cher, a dust-collecting device eonsisting of an outerwall of foraminous material, and an axially disposed inner cone offoraminous material connecting at its base with the adjacent end of theouter Wall, and dust-collecting material on said cone and the wall.'

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
